Can depression make you tired?

            Thank you for your question, reader. Feeling fatigued and having low energy are symptom criteria for a major depressive episode according to the DSM-V (the manual that mental health professionals use to diagnose mental illness). In my experience, people experience fatigue and low energy during a depressive episode in a couple of different ways.

            People who suffer from depression can have bouts of insomnia or experience lower quality sleep. This can lead to tiredness during the day on top of bodily fatigue that accompanies depression for many. Some people with depression describe a feeling of “heaviness,” and many reports having little energy. Some people feel so tired that they have difficulty getting out of bed. These can all be symptoms of depression, which is caused by changes in brain chemistry.

            People with depression can also experience a type of mental fatigue. This can show up as low motivation for normal interests and activities. Some people have a loss of concentration and focus during times of depression and difficulty in making decisions.

How does depression cause tiredness?

            Depression is likely associated with changes in brain neurotransmitters, such as dopamine, norepinephrine, and serotonin. "These neurotransmitters play important roles in regulating energy levels, sleep, appetite, motivation, and pleasure," according to a quote from Amy Ricke, MD (https://www.insider.com/why-does-depression-make-you-tired). So, there are imbalances at work in the brain that are causing symptoms of tiredness, low energy, loss of motivation, and contribute to you feeling all around down. Stephen Hayes Ph.D. refers to symptoms such as the “pain of presence” or experiences you have that cause suffering. Behavioral changes related to depression also come into play. Examples of these losses include not seeing the people you usually find yourself laughing with or not going to a job that normally gives you feelings of satisfaction. The lack of mood-boosting activities and interests resulting from depression Hayes refers to as “the pain of absence.” Lack of stimulation and activity is a part of the negative spiral that can intensify how tired and unmotivated you may already feel.

            Depression is a serious condition that causes suffering and makes it difficult to participate in your life. If you or others around you recognize symptoms of depression, it is important to seek help from a mental health professional.
